Available in PDF, EPUB and Kindle. Book excerpt: Considering the increasing global prevalence of overweight and obesity and their propensity for disease, this study was undertaken in an attempt to optimize exercise prescription for this at-risk group by determining if the benefits associated with interval training occur in an intensity dependent manner. 19 sedentary, overweight males (Age: 22.7 ± 3.9 yrs, BMI: 31.4 ± 2.6 kg/m2, WC: 106.5 ± 6.6 cm) performed interval training for three weeks at either 70% or 100% of their peak work rate on a cycle ergometer. Aerobic capacity measurements, time to completion trials, muscle biopsies, and fasted blood samples were all performed pre and post training. Analyses of aerobic capacity and exercise performance demonstrate greater improvements made in the 100% compared to the 70% group, while measures of skeletal muscle oxidative capacity indicate equivalent changes between groups. Taking into account the similar increases in mitochondrial content in both groups and understanding the influence of both oxygen supply and demand in determining maximal oxygen consumption, the greater increases in aerobic capacity achieved by the 100% group may be the result of enhanced cardiovascular adaptations. These findings suggest that some of the health benefits associated with interval exercise may be intensity dependent. Therefore, there may be additional benefit to exercise at higher intensities.

Madden and published by . This book was released on 2018 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: The purpose of the current study was to determine if obesity affects the excess post-exercise oxygen consumption (EPOC) values and caloric expenditure (CE) after a single bout of high intensity interval exercise (HIIE). Twenty adults (12 men and 8 women) were divided into two groups based on BMI: obese (OB) or non-obese (NOB). All subjects completed a single 20 min HIIE bout on a Velotron cycle. Intervals were 1 min of exercise at 85-85% HRmax followed by 1 min of rest. Oxygen consumption was measured post exercise to estimate EPOC and CE. There was a significant difference in the absolute total EPOC (L) between OB (M = 3.80, SD = 1.27) and NOB (M = 2.40, SD = 0.88) groups, t(18) = 2.88, p = .01, d = -1.29. There was a significant difference in CE (kcal) between OB (M = 19.03, SD = 6.35) and NOB (M = 11.99, SD = 4.41) groups; t(18) = 2.87, p = .010, d = -1.29. No significant mean differences were found in time (min) spent in EPOC and absolute magnitude (L/min) between OB and NOB. A medium effect size was found with time spent in EPOC (d = .64) and the absolute magnitude (d = .69) between NOB and OB groups. Differences between OB and NOB groups may be attributed to the total mass of an individual while relative values seem to be similar between groups.
Book Synopsis The Effect of High-intensity Interval Training (HIT) on Gut Microbiota in Humans by : Julia Cree
Download or read book The Effect of High-intensity Interval Training (HIT) on Gut Microbiota in Humans written by Julia Cree and published by . This book was released on 2018 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the light of rising obesity rates and the increasing incidence of metabolic disease which contributes significantly to both global and local health problems, novel approaches to reduce the burden of disease must be explored. It is now widely acknowledged that gut microbiota can affect host metabolism, and its composition and activity are an important influence on overall health. Whilst exercise and physical activity have long been recognised as a way to prevent or delay numerous chronic conditions, emerging evidence from rodent studies, supported by limited research in humans suggests that modulation of gut microbiota may be one of the potential mechanisms that exercise improves health. The purpose of this study was to investigate the effect of a high-intensity exercise intervention on the gut microbiota of lean and overweight/obese, healthy adult males in Auckland, New Zealand. Participants were recruited to either lean (BMI 25) or overweight/obese (BMI 28) groups for nine high-intensity interval training (HIT) sessions over 3 weeks. Gut microbiota composition, cardiorespiratory fitness, blood and fecal biomarkers of metabolic and inflammatory health were measured pre and post intervention with the ultimate goal of increasing the understanding of how possible exercise mediated changes in gut microbiota may improve metabolic health. Overall results demonstrate that while a short term HIT intervention is limited in its capacity to modify the composition of gut microbiota in healthy young men, and did not change the body composition of participants or blood or fecal biomarkers of metabolic and inflammatory health, it is an effective exercise protocol for improving cardiorespiratory fitness irrespective of BMI. Changes in fecal pH observed indicate HIT can bring about modifications in the gut, dependent on BMI status. Our analysis of gut microbiota revealed limited compositional differences between BMI groups at baseline line and as a consequence of HIT. We did not demonstrate any significant changes in gut microbiota, apart from an increase in Faecalibacterium prausnitzii in lean participants. Inter- and intra-subject variation presents vast challenges in determining the effect of HIT on gut microbiota composition and it remains unclear whether HIT is a useful strategy in this regard.
Book Synopsis Effects of Eight Weeks of High-intensity Interval Training on Blood Glucose Control, Endothelial Function, and Visceral Fat in Obese Adults by : Brandon J. Sawyer
Download or read book Effects of Eight Weeks of High-intensity Interval Training on Blood Glucose Control, Endothelial Function, and Visceral Fat in Obese Adults written by Brandon J. Sawyer and published by . This book was released on 2013 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cardiovascular disease (CVD) is the number one cause of death in the United States and type 2 diabetes (T2D) and obesity lead to cardiovascular disease. Obese adults are more susceptible to CVD compared to their non-obese counterparts. Exercise training leads to large reductions in the risk of CVD and T2D. Recent evidence suggests high-intensity interval training (HIT) may yield similar or superior benefits in a shorter amount of time compared to traditional continuous exercise training. The purpose of this study was to compare the effects of HIT to continuous (CONT) exercise training for the improvement of endothelial function, glucose control, and visceral adipose tissue. Seventeen obese men (N=9) and women (N=8) were randomized to eight weeks of either HIT (N=9, age=34 years, BMI=37.6 kg/m2) or CONT (N=8, age=34 years, BMI=34.6 kg/m2) exercise 3 days/week for 8 weeks. Endothelial function was assessed via flow-mediated dilation (FMD), glucose control was assessed via continuous glucose monitoring (CGM), and visceral adipose tissue and body composition was measured with an iDXA. Incremental exercise testing was performed at baseline, 4 weeks, and 8 weeks. There were no changes in weight, fat mass, or visceral adipose tissue measured by the iDXA, but there was a significant reduction in body fat that did not differ by group (46±6.3 to 45.4±6.6%, P=0.025). HIT led to a significantly greater improvement in FMD compared to CONT exercise (HIT: 5.1 to 9.0%; CONT: 5.0 to 2.6%, P=0.006). Average 24-hour glucose was not improved over the whole group and there were no group x time interactions for CGM data (HIT: 103.9 to 98.2 mg/dl; CONT: 99.9 to 100.2 mg/dl, P>0.05). When statistical analysis included only the subjects who started with an average glucose at baseline> 100 mg/dl, there was a significant improvement in glucose control overall, but no group x time interaction (107.8 to 94.2 mg/dl, P=0.027). Eight weeks of HIT led to superior improvements in endothelial function and similar improvements in glucose control in obese subjects at risk for T2D and CVD. HIT was shown to have comparable or superior health benefits in this obese sample with a 36% lower total exercise time commitment.

Book Synopsis The Impact of Lifestyle Changes on Non-communicable Diseases by : Giulia Marrone
Download or read book The Impact of Lifestyle Changes on Non-communicable Diseases written by Giulia Marrone and published by Frontiers Media SA. This book was released on 2024-09-09 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-communicable diseases (NCDs) are the first cause of death in the world. In the pandemic era, patients affected by NCDs were more susceptible to contracting the infection and developing its most severe clinical pictures. The widespread diffusion of NCDs is partly related to incorrect eating habits and a sedentary lifestyle that characterize developed Countries. This phenomenon can also be attributable to the epidemiological transition, which has caused the NCCDDs spread also in developing Countries. Among NCDs, chronic kidney disease (CKD), cardiovascular diseases (CVDs), and cancer are the most notable. In fact, the first one is characterized by a pervasive spread and it was hypothesized that in 2040, CKD will become the fifth most common cause of death in the world. Currently, CVDs are the main cause of death in the world, taking an estimated 17.9 million lives each year.

Book Synopsis Exercise and Diabetes by : Sheri R. Colberg
Download or read book Exercise and Diabetes written by Sheri R. Colberg and published by American Diabetes Association. This book was released on 2013-05-30 with total page 554 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical movement has a positive effect on physical fitness, morbidity, and mortality in individuals with diabetes. Although exercise has long been considered a cornerstone of diabetes management, many health care providers fail to prescribe it. In addition, many fitness professionals may be unaware of the complexities of including physical activity in the management of diabetes. Giving patients or clients a full exercise prescription that take other chronic conditions commonly accompanying diabetes into account may be too time-consuming for or beyond the expertise of many health care and fitness professionals. The purpose of this book is to cover the recommended types and quantities of physical activities that can and should be undertaken by all individuals with any type of diabetes, along with precautions related to medication use and diabetes-related health complications. Medications used to control diabetes should augment lifestyle improvements like increased daily physical activity rather than replace them. Up until now, professional books with exercise information and prescriptions were not timely or interactive enough to easily provide busy professionals with access to the latest recommendations for each unique patient. However, simply instructing patients to “exercise more” is frequently not motivating or informative enough to get them regularly or safely active. This book is changing all that with its up-to-date and easy-to-prescribe exercise and physical activity recommendations and relevant case studies. Read and learn to quickly prescribe effective and appropriate exercise to everyone.

Book Synopsis Perceptual Responses to High Intensity Interval Training Among Overweight and Obese Individuals by : John Thomas Halvorson
Download or read book Perceptual Responses to High Intensity Interval Training Among Overweight and Obese Individuals written by John Thomas Halvorson and published by . This book was released on 2016 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: Poor diet and exercise adherence is resulting in the rise of chronic diseases. High intensity interval training (HIIT) has the ability to improve adherence as it takes less time to complete and has changes in intensity and monotony. The aim of the study was to analyze whether participants prefer HIIT in comparison to continuous aerobic exercise (CON). The hypothesis was that HIIT would be preferred and enjoyed more than CON both during and following the exercises. Participants were men and women (n=14) between the age of 30-55 years with a BMI of 25-35 kg/m2. Participants completed three exercise conditions: CON) a 45 minute walk at 60% of age predicted maximal heart rate (APMHR), HIIT60) a 20 minute HIIT exercise in which the speed and incline was changed between a high intensity of 80% APMHR and 60% APMHR every 60 seconds for a total of 10 cycles, and HIIT90) a 21 minute HIIT exercise in which the speed and incline was changed between a high intensity of 80% APMHR and 60% APMHR every 90 seconds for a total of 7 cycles. Heart rate (HR), exercise enjoyment during the exercise as measured by the exercise enjoyment scale (EES), and ratings of perceived exertion (RPE) were collected at multiple time points during the exercise. Five minutes of post exercise oxygen consumption was measured immediately and 30 minutes following the exercise sessions. General feelings as measured by the feeling scale (FS) and physical activity (PA) enjoyment as measured by the physical activity enjoyment scale (PACES) was measured 5 minutes and 35 minutes following the exercise sessions. HR and RPE were both higher in HIIT60 and HIIT90 compared to CON. In task exercise enjoyment was not higher between conditions. PA enjoyment was higher in both HIIT60 and HIIT90 compared to CON 5 minutes following the exercises. General feelings in HIIT60 was the only condition to increase 35 minutes compared to 5 minutes following the exercise. We conclude that HIIT is a more preferred exercise than CON as shown by higher preferences for HIIT90 and HIIT60 as well as higher ratings of post exercise PA enjoyment.
